MACHINE FORCONSTRUCTING IRRIGATING OR OTHER PIPES.

SPECiIFIGA'IION forming part of Letters Patent No. 639,858, dated December 26, 1899.

Application fllecl March 29,1899.

To all whom it may concern.-

Be it known that we, JOSEPH H. MARTIN and DAVID ORMAND, of Riverside, in the county of Riverside and State of California, have invented a new and Improved Machine for Constructing Irrigating or other Pipes, of which the following is a full, clear, and exact description.

The object of this invention is toprovide a machine especially adapted to make a continuous concrete pipe of sand and cement or other Suitable material either for water, sewer, or electric'conduitsand to produce said pipe in a simple and economic manner and to so construct the machine that the material lltllized will be shaped and set by a single operation of a lever oralike device. 4 p

A further object of the invention is to provides; means whereby the material will be distributed in an evenand compact manner.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

' found desirable.

in which similar characters of reference indicate corresponding parts in all the figures.

- Figure 1 is a side elevation of the improved machine. Fig. 2 is a transverse section taken practically on the line 2 2 of Fig. 4. Fig. 3 is a transverse section taken on the line 3 3 of- Fig. 4. Fig. 4 is a longitudinal vertical sec-- tion through the entire machine. Fig. 5 isa transverse section taken on the line 5 5 of Fig. 4, and Fig. 6 is a plan view of the hopper and tampin g device.

The body-or easing A of the machine is circular in cross-section and is provided at its forward end with a spider 10 and also with an intermediate spider 11; but disks may be substituted for the spiders if in practice it be. An opening is made in the upper portion of the casing A, leading into a chamber 13, into which the cement andsand oroth'er material from which the pipe is to be manufactured is tamped. The opening leading into the tamping chamber 13 is provided with a suitable hopper 12. The end walls of the chamber 13 are formed through the medium of two disks 14 and 15, placed a suit- .upward, guided by said guide-bars.

able distance apart, said disks being of less diameter than the diameter of the casing A, and said disks are centered in thecasing, the spaces between the inner peripheries of the disks and the inner surface of the casing being nearly the thickness of the pipe to be made.

The camping device 0 employed is best shown in Figs. 2 and .6, and consists of the following parts: Guide-rods 17 are secured longitudinally upon opposing inside surfaces of the hopper 12, and a tamping-plate 18 is located between the guides, mounted to turn upon a spindle 19, provided with a fork 19 at each end, said forks loosely receiving the guide-rods 17. AA link 20 is pivoted to the .forward edge portion of the plate, one near each end, a'nd each link is provided with a downwardly-extending rigid arm 18, and in the horizontal or working position of the tamping-plate the arms 18 are immediately over it, as shown in Fig. 4. The'upper ends of-thelinks are pivotally attached to levers 21, pivoted to ofisets 22 from the forward face of the-hopper, and these levers are connected by a handle-bar 23. In the operation of this part of the machine, supposing the hopper to contain cement and the tamping-plate to be at. its lowest position in the cement, when the handle-levers are raised and carried forward the links are drawn upward and will turn the tamping-plate upon. its pivot until the plate occupies a vertical position between the guide-bars. Meanwhile the plate is also drawn Thus the plate can be readily drawn through the ocment to a point above it.- Upon the downstroke of the hand levers and links the tamping-plate is gradually restored to its horizontal position and will be forced downward in such position for a considerable distance, be-

ing prevented from turning by the projecting to force the cement or materialfrom the tamping-chamber 13 into the space between the rear disk-wall of said chamber and the casing. The cementplunger Bis mounted to slide over-a tubular shaft 16, which is attached to the spiders 10 and i the casing I and to the walls 14 and 15 of the tampingchamber, holding said walls in place, and the cement-plunger is likewise adapted to slide over the disk forming the forward wall of said tamping-chamber, as is shown in Fig. 4. The cement-plunger is connected by rods 24 with a yoke 25, said yoke being secured to the rear end portion of a piston-plunger D, which comprises a solid head 26 and a tubular body 27. The piston-plunger D is mounted to slide in a hydraulic cylinder E of any approved construction, and said cylinder is supported on wheels 28, journaled at its sides.- The cylinder is provided with a valve 29, of ordinary construction, to control the supply of liquid to the piston-plunger, and said valve 29 is preferably worked by hand, a lever 30 being attached to the valve-stem,

as shown in Fig. 4. The lever is operated. through the medium of a link 31, that is carried rearward through suitable guides at one side of the hopper, as shown in Fig. 1.

Connecting-rods 33 are employed to attach the forward end of the casing A to the rear end of the hydraulic cylinder, and these rods also serve as guides for the yoke 25 of the piston-plunger passing through recesses 32 in'theperiphery of the yoke, as shown in Fig. 3. These connecting-rods 33 also serve to prevent the piston-plunger from turning during its operation.

The hollow body 27 of thepiston-plunger is mounted to slide over a cylinder 34, which is provided with peripherally-located spiral grooves 35, usually two in number, and the grooves extend from end to end of the cylinder. Pins 36, carried by the body of the piston-plunger, enter the grooves. 35, thereby imparting a rotary movement to the cylinder at each stroke of the piston-plunger. A shaft 35 is secured at one of its ends in the cylinder 34, and said shaft is passed through ball-bearings 36, located at the forward end of the casing A and through the tubular shaft 16 and out beyond the rear end of said shaft into a revolving core F, located at the rear of the rear wall of the tamping-chamber 13. This revolving core is in the form of a cylinder closed at one end, the forward end being in engagement with the flange of the wall 14 of said tam pin gchamber 13, as shown in Fig. 4.

A ratchet-wheel 38 is secured to the end of the shaft 35, extending into the revolving core, anda dog 39, pivoted upon the end wall of the revolving core, is in engagement with the ratchet-wheel 38. When the piston-plunger moves rearwardly to cause the cement-plunger to force material from the tamping-chamber, the pins,tra'veling in the grooves 35 of the cylinder 34, cause the shaft? 35 to revolve sufiiciently to impart a halft-urn to the revolving core through the medium of the ratchet-wheel 38 and dog 39; but upon the return stroke of the piston-plunger the dog glides over the ratchet-wheel and has no action thereon. The exterior surface of the revolving core corresponds to the interior diameter of the pipe that is to be constructed. The rear end of the shaft 35 is preferably supported in ball-bearings 37, as is sh own in Fig. 4.

Asliding form A, adapted to shape the outside of the pipe, is employed in connection with the casing A, telescoping the rear end of said casing. The form A is free to slide on the casing, but is connected with the easing through the medium of rods 40, pivotally attached to the forward portion of the form A at each side, each rod being provided with a link 41, and these links extend forwardly along the outside surfaces of the casing, as shown in Fig. 1, and receive pins 42, projected from the side of the cement-plunger outward through slots 43 made in the casing. At the rearward movement of the piston-plunger the form A remains still, while the other part of the machine is pushed forward a distance proportionate to the amount of material that has been tamped into said form by the cement-plunger. At the return stroke of the piston-plunger the studs 42, by engagement with the forward ends of the links 41, will gradually draw the form back to its initial position relative to the casing. I

In operation the cement, mortar, or concrete is thrown into the hopper 12 and thus conducted to the chamber 13, in which chamber it is well packed by the tamping device 0. Through the medium of the lever 31 the valve in the hydraulic'cyliuder is shifted in a manner to direct the pressure into the forward end of the cylinder E-,which action forces the piston-plunger D rearward, imparting a like movement to the cement-plunger B,causing it' to push through the chamber 13' and force the mortar or cement in between the core 1 and sliding form A, where it is compressed by the pressure of the plunger B and the friction of the mortar or cement between 4 said core F and the sliding form A. While the plunger B is being pushed through the chamber 13 the core is made to revolve a halfturn at each stroke by means of the pins 36, the cylinder 34, the shaft 35, the ratchet 38, and dog 39. While the cement or mortar is being tamped in the mold, consisting of the core F and form A, the form A remains still, while the other or supply section of the machine is pushed forward by the measure of the material that has been tamped in by the plunger.

By reason of the friction of the, mortar or cement against the sides of the form A mortar or cement is prevented from being pushed through it, and thereby breaking the pipe already made, and this friction is great enough to force the other or supply section ofthe ma chine ahead. When the piston-plunger is at the limit of its rearward stroke, the valve 29 is shifted to bring the pressure at the rear of the hydraulic cylinder and the piston-plunger is carried forward, the two plungers moving in the same direction; but the core F remain-s stationary, since the dog 39 will slip over the ratchet-wheel 38. The sliding form A, through the medium of the links-41 and pins 42, is pulled forward at every stroke of the piston-plunger just as far as the machine is moved forward. Loose earth is thrown around the form A to a point a little above the centerand is thoroughly tam ped. This supports the sides of the pipe and keeps the crown from falling when the machine is moved forward.
